What is the minimum voltage of a 26650 lithium battery?

Introduction What is the minimum voltage of 26650 lithium battery? 26650 lithium battery is mainly divided into two types: ternary material and lithium iron phosphate material. The ternary material 26650 lithium battery is fully charged.

What is the minimum voltage of a 26650 lithium battery?

The 26650 lithium battery is mainly divided into two types: ternary material and lithium iron phosphate material. The full charge voltage of the 26650 lithium battery of the ternary material is 4.2V, and the full charge voltage of the 26650 lithium iron phosphate battery is 3.65V; Therefore, the minimum operating voltage of 26650 lithium battery depends on the application, as follows:

1. Ternary 26650 lithium battery material: 1. 26650 ternary lithium battery cell. The discharge cut-off voltage is 2.75V, that is, the discharge voltage Minimum operation of a single battery cell is 2.75 V.

2. If 26650 lithium batteries are assembled in series and parallel to form a PACK, the minimum voltage for a single bank is 2.75 V multiplied by the number of series connections.

2. 26650 lithium iron phosphate battery:

1. If itThe is used without protection plate, the discharge cut-off voltage of 26650 lithium battery cell is 2.0V.

2. If 26650 lithium batteries are assembled in series and parallel to form a PACK, it is recommended that the discharge cut-off voltage of a single string is 2.5V, that is, the voltage minimum used is 2.5 V. 2.5 V multiplied by the number of series connections. Of course, it must also be combined with the performance of the specific parameters of the corresponding PACK protection card.

The above answer from dianchizhidu is for your reference, hope it is helpful for you.

It is generally believed that the minimum discharge voltage of lithium batteries is about 3.0V, and the minimum discharge voltage cannot be lower than 2.5V, otherwise it could cause permanent damage.

In fact, the protective voltage against discharges ofLithium batteries used in cell phones are set at around 3.4-3.6 V. The phone will automatically turn off when this voltage is reached.
